' i all whom it may concern:

Be'it known that L'PAUL B. RARE, a citizen of the United States,residing at- Chicago,".i n the county of Cook and State ofn Illinois,have invented a certain new and useful Improvement in Storage Batteries,-(Case 4,) of which the following is a full,

-' clear, concise, and exact description, refer' ence being bad to theaccompanying draW- cell embodying certaln improvements of my in 'sformin a art of this soecification. a a a p p l I My invention relatesto storage batteries,

Y and broadly stated, is concerned with certam improvements in the meansfor and [manner of mounting and supporting the .grids Within a storagebattery cell. 1n the arrangement hereinafter described and subsequentlyclaimed, the several grids are so disposed and carried Within thestorage battery cell that it is possible to dispense .With the spacersWhich are ordinarily inter-- posed between grids of opposite polarity.

improved storage battery cell is further- .morecharacterized by itscompactness.

a description ofimy invention will be best understood when read inconnection I With the drawings illustrating the same, I

.shall proceed With a description of the accompanying drawings, inWl1lCl-- Figure l is an axial sectional View of a storage battery cellembody ngthe lIl'llJI'OX'Q fnients ofmy invention;

:f nthe line 2-2 of Fig. 1'; and g 'F1g, 3 is a vertical sectional viewillus- Fig. 2'is a horizontal sectional View taken trating a modifiedform of storage battery invention.

Similar characters of reference refer to similar parts throughout theseveral views.

- In Figs. "land 2 the receptacle constituting'thecell container isillustrated at 10, and atllis illustrated asuitable closure therefor.,l'lheidetails of the receptacle are unim'pon 5 taut, save that i vdesirable that it begenerally square, or rectangular 111 form inorderthat the grid-plate liners may be conven-j -iently mounted therein aspresentl de-- scribed.

, At 12,13, 14:, and 15 I have illustrated four grid plates which aredisposed against the inner surfaces of the side Walls of the receptacle10} 'and thus in effect constitute lining for the receptacle. The gridplates mentioned are similar. in all respects except that plate 12ispjifovided ivith anupwardlyextending. arni I2 wheres a suitable ter-"tcrminal of the cell.

T he outer faces of the grid D 14 and 15 thatis, thelfac'es whicliContact with the s de Walls ofjtlie receptacle are imperiforate. Formedin the inner face of each of said grid plates isa plurality of 3 cells16, 16 adapted to receiveiany isuitflble and well-known grid paste. fIt'wrill be noted that the upperand loive 'walls of each of the cells 16incline downwardly froni "the inner face of the plate, sotliatfltheie Vor no tendency for the grid-paste to 'fall' out of the cells. Thecellshre' c t'invenientlvarranged in ranks and files andareevenlydistributed' over the ini" plates. F

The grid plates 12, posed Within the recept-aclefirith their lateraledges overlapping, (as illustrated" in Fig. 2. The edges thus"overlapped and abutting are connected mechanically "andelectrically byfusing "or: burning the parts together, Which is of cours'ereadilyaccomplished, as the 'gridplat an alloy having a compa a point. 1. p

In so far as my inventionis-concerned, it

is unimportant Whethenthe r'id late's' 'ust described be preparedasinegative or .po'sitive plates, although Iprefe'r thattheyshallconstitute the" negative plates. 1' shallnow" proceed to describeWhat'vvill constitute the positive side of the c'ellfl j Centrallylocated on tliebottoni of the cell receptacle, and securedthefetobyfscrews or otherwise is a porcelain rest 17 provided with anupstanding boss 1 8ffHavingits is, Ira-mi 1 5 area-a- I D er -1 finlower end providedwith asocket fitting over the boss 18 is ai ed-19,theiupper end of which, square in cross section, passes through acorrespondingly "shaped-aperture in the closure 11 and constitutes thepositive This rod is provided intervals of. 90 degrees, into'fsaid slotsare the grid plats'ZO; 20', each of which particularly adapted for usein this connecof the grid plates 20, 20 is not of particular importanceas long as said grid-plates are capable'of properly carrying sufficientpaste and of exposing a sufiicient area thereof to the electrolyte,which, for the sake of clearness in illustration, has been omittedfromthe drawings. I will say, however, that the particular grid platestructure shown and described in my co-pending application, Serial N 0.293,603, filed April 30th, 1919, is

tion. It is to be understood that in practice the receptacle will befilled with any suitable liquid or non-liquid electrolyte.

' to constitute a unitary grid plate liner for' It will be seen that thepositive and negative grid plates are supported in such a manner that isis unnecessary to provide wood or other non-conducting spacers betweenthe positive and negative plates, and furthermore, that either thepositive or negative plates may be removed as a unit for inspection orrepair without disturbing the mounting of the plates of oppositepolarity. In the modified form. of storage battery cell illustrated inFig. 3, both thepositive and negative removable grid plate structuresare substant1al1y similar to the negative grid plate structure shown inFigs.

1 and 2. Therefore in Fig. 3 I have applied the same reference numeralsto the several parts as have been applied to corresponding parts in thearrangement of Figs. 1 and 2. The arrangement shown in Fig. 3 isparticularly advantageous in that the cell is compact and in that boththe positive and negative grid plate structures may be inserted andremoved as units for purposes of inspection and repair.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent of the United States is:

.1. A storage battery cellof the class described comprising arectangular receptacle,

a plurality of grid plates, one disposed against each side Wall of thecell receptacle with ad acent' lateral edges of saidgrid plates abuttingand being burned together said receptacle, a plurality of downwardlyinclined paste-receiving cells formed in the inner surface of each ofsaid grid plates, a cover for said receptacle, a centrally disposedsupporting-st'ud carried by the'bottom of said receptacle, a rod oflow-fusing metal provided at its lower end with a socket fitted oversaid stud and having its upper end extending through said cover," aplurality of longitudinal slots in said rod, a plurality of grid plates,each having one of its lateral edges fitted in one of said longitudinalrecesses and secured thereto by being burned to the rod, said lastmentioned grid plates radiating from said rod.

2. A storage batterv cell comprising in combination with a cellreceptacle a unitary pasteereceiving grid plate lining for the innersurfaces of the receptacle side walls, a

rod oflow-fusing metal vertically and centrally disposed in saidreceptacle, a plurality of longitudinal slots in said rod, a pluralityof paste-receiving grid plates each having one of its lateral edgesfitted in one of said slots and secured therein by being burned to saidrod, said last-named plates radiating from said rod substantially asdescribed.

3. A storage battery cell'comprising in combination with a cellreceptacle, grid plates of one polarity supported within saidreceptacle, a rod of low-fusing metal verti-- cally disposed in saidreceptacle, a plural- .ity of longitudinal slots in said rod, aplurality of vertically disposed grid plates each having one of itslateral ed es fitted in one of said slots and secured therein by being fburned to said rod, said last mentioned grid plates radiating from saidrod, said last mentioned grid plates being of different polarity thanthe grid plates first mentioned.

4. A storage battery cell of the class described comprising invcombination with a rectangular cell receptacle, a plurality of pastereceiving grid plates lining the inner surfaces of thereceptacle sidewalls, a rod of low-fusing metal vertically disposed in said receptacle,a plurality of longitudinal slots in said rod, a plurality ofpastereceiving grid plates each having one of its lateral edges fittedin one of said. slots and secured therein by being burned to said rod,said last mentioned plates radiating from said rod. I

5. A storage battery cell of the class described comprising incombination with a rectangular cell receptacle, paste receiving gridplates lining the inner surfaces of the receptacle side walls, a'rodvertically and centrally disposed in said receptacle together with fourvertically disposed paste receiving grid plates carried by said rod,each of said grid plates having one of its lateral edges attached tosaid rod and radiating from said rod toward one of the four corners ofthe receptacle. v v

In Witness whereof, I-hereurrto. subscribe my name this 22 day of April,19-19.
